Geum plant named ‘Cherry Bomb’

ABSTRACT

A new, distinct Geum plant as illustrated and described, characterized by ruffled semi double to single pink flowers.

Latin name: Geum hybrid.

Cultivar name: ‘Cherry Bomb’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid of Geum plantnamed ‘Cherry Bomb’ characterized by ruffled semi double to single pinkflowers. The new Geum was discovered and developed as a seedling as partof an ongoing breeding and selecting program in Hebron, Ill. in 2010.The plant was raised from seed on open pollinated plants. The parents ofthe new plant are unknown. The selection of the new plant was made in2014 and was due to its' ruffled semi double to single pink flowers. Theinitial asexual propagation of the new Geum plant was by division andtook place at a nursery in Hebron, Ill. since 2015. Continued asexualpropagation by division since that time has shown that the uniquefeatures of the new Geum plant are stable and reproduced true to type insuccessive generations. No plants of the new Geum have been sold in thiscountry, or anywhere in the world, prior to the filing of thisapplication, nor has any disclosure of the new plant been made prior tothe filing of this application with the exception of that which wasdisclosed within one year of filing of this application and was eitherderived directly or indirectly for the inventor.

SUMMARY OF THE INVENTION

In the following description, color references are made to The RoyalHorticultural Society Colour Chart (2001). The new Geum plant named‘Cherry Bomb’ characterized by semi double to single flowers of pink RHS185 C and 185 D fading to 159 A at the tips of the petals have beenobserved to be unique and stable. The parent plants are no longeravailable for comparison.

Plants of the new Geum can be compared to Geum ‘Mai Tai’ U.S. Plant Pat.No. 22,433, patented. 1. The new plant flower color is pink RHS 185 Cand 185 D fading to 159 A at the tips of the petals while Geum ‘Mai Tai’has a flower colors of RHS 53 B fading to 48 C and finally to 36 B and36 C.

Plants of the new Geum can also be compared to Geum ‘Sangria’ notpatented. 1. The new plant flower color is pink RHS 185 C and 185 Dfading to 159 A at the tips of the petals while Geum ‘Sangria’ has aflower color of RHS 45 B. 2. The new plant also has flowers that measure4 cm wide while Geum ‘Sangria’ has flowers that measure 5-6 cm wide.
